#2Does this new intel CPU have 'fixes' for all issues like spectre and meltdown, where you were supposed to turn off hyperthreading for better security? I'm just curious if the fixes for those (and other similar vulnerabilities) are starting to make their way into silicon, but also that the fixes recommended usually slow cpu's down quite a bit too.

#3this doesn't quite pass the smell test. I can't quite tell if there's a way to filter out results from overclocked parts in geekbench, but it looks like these results for the i9-10900F are significantly lower than typical results for a stock i9-9900K. hard to believe they would do worse on the same process with more cores.

It is worth noting that this is the i9-10900F, not the i9-10900k (thank you, Intel, for the lovely naming scheme). I'd expect the -k variant to be at least as fast as the i9-9900k.

Coffee Lake and newer has mitigations for that apparently.

I'm unsure if a "fix" is actually possible with a pure hardware solution.

It also doesn't pass the smell test in that the single core performance is higher than the Ryzen 4900 and it also has both more cores and more threads yet it is far behind on multicore performance?
Likely some thread affinity issue that just needs a patch.

Not sure how that will matter, F just means there are no integrated graphics. Why would that impact performance compared to a i9-9900 ?

I believe the K variant also has a higher base clock (3.7 vs. 3.2)

Also, 9900 was much easier to say... how do you pronounce 10900? "Ten-thousand-nine-hundred"? Feels tortured. "Ten-nine-hundred"? Yeesh.
